(2 STATION INDICATORS
The indicator that corresponds to the STATION CALL
switch which has been depressed lights.
NOTE:
When presetting a station, all six indicators light in sequence for

48 STATION CALL SWITCHES

2) MEMORY/STOP SWITCH

the STATION CALL switches.
@ TUNING SELECTOR
This is used to select the reception mode.
STATION SCAN (released position):
When the TUNING switch is depressed, the broad-
Casting stations start to be scanned and this procedure
stops once a station has been picked up. The program
of that station is heard for about 5 seconds. The tuning
operation then resumes and sound is heard in the same
way. Each of the stations is thus picked up in turn.
When the MEMORY/STOP switch is depressed once
you hear the sound of the desired program, the tuning
operation stops and the unit is set to the reception
mode.
MANUAL (depressed position):
For manual tuning. Depress the TUNING switch and
tune in the station manually, each time the TUNING
switch is depressed, the frequency changes in 100kHz
steps during FM reception and in 10kHz steps during
AM reception. When the TUNING switch is kept de-
pressed, the frequency is continuously scanned. Tuning
stops when the upper or lower limit of the frequency
band id, reached.
NOTE:
AM CHANNEL STEP switch on the rear panel should be set
to correct (10kHz) position.
This is depressed when using a tape deck or adaptor unit
connected to the rear panel TATE One ton jacks.
@) MONO MUTE OFF SWITCH
The sound is heard in mono when this switch is set to the
depressed position. Normally, the switch is kept at the
released position. During the FM reception, the noise is
reduced and reception is made clear. When the station is
distant and its signals are weak, depress the switch and
tune in the station manually.
@) LOUDNESS SWITCH
When listening to a performance with the VOLUME level
is low, depress this switch and the bass and treble will be
accentuated.
When the volume is low, the human ear finds it harder to
hear the bass and treble than when the volume is high.
The LOUDNESS switch is thus designed to compensate
for this deficiency.
